Struct FixedPointScratch 

pub struct FixedPointScratch { /* private fields */ }

Caller-owned scratch for Weir fixed-point GPU wrappers.

Implementations

impl FixedPointScratch

pub fn with_capacities( frontier_words: usize, output_slots: usize, resource_slots: usize, ) -> Result<Self, String>

Allocate reusable fixed-point scratch with enough retained capacity for a known hot loop shape.

frontier_words sizes both the current and next frontier word buffers. The byte frontier buffer is pre-sized to the exact little-endian byte representation capacity used by dispatch wrappers. output_slots preallocates reusable backend output vectors, and resource_slots preallocates the dispatch resource list plus retained static input byte slots for invariant graph buffers.

pub fn clear(&mut self)

Drop logical contents while preserving allocation capacity.

pub fn output_slot_count(&self) -> usize

Number of backend output slots currently retained by this scratch.

pub fn output_slot_capacity(&self) -> usize

Current retained capacity for backend output slots.

pub fn static_input_slot_capacity(&self) -> usize

Current retained capacity for static dispatch input byte slots.

pub fn frontier_byte_capacity(&self) -> usize

Current frontier byte-buffer capacity retained by this scratch.

pub fn frontier_word_capacity(&self) -> usize

Current frontier word-buffer capacity retained by this scratch.

pub fn next_word_capacity(&self) -> usize

Current decoded-next-word capacity retained by this scratch.

pub fn resource_capacity(&self) -> usize

Current dispatch resource-list capacity retained by this scratch.

pub fn alternate_resource_capacity(&self) -> usize

Current alternate dispatch resource-list capacity retained by this scratch.

pub fn edge_kind_mask_capacity(&self) -> usize

Current filtered-edge-kind mask capacity retained by this scratch.

pub fn reverse_offset_capacity(&self) -> usize

Current reverse-CSR offset capacity retained by this scratch.

pub fn reverse_target_capacity(&self) -> usize

Current reverse-CSR target capacity retained by this scratch.

pub fn frontier_density(&self) -> FrontierDensityTelemetry

Latest fixed-point frontier density counters for this scratch session.
